They have a good description on the website of their process. The recruiter will screen first. Based on their impressions, a technical interview comes next. This is specific to the type of work that you do, and the questions will vary based on what type of IT consulting work you do. There may be additional technical interviews. If approved, behavioral interviews take place. This is with at least three people. Each person has a series of questions and is evaluating for company/culture fit on different values. A decision is made at the end of the behavioral interviews if the person will be hired or not, or if they may be placed on hold for contacting at a later time when an opportunity comes up.
